Description of the Related Art When rivets are used for caulking and fastening synthetic resins or a combination of synthetic resins and various metal plates (steel plates, alloy plates, etc.), the caulking head of the rivet 111 is pressed in the axial direction. Then, as shown in FIGS. 19 to 21, the body diameter of the rivet 111 swells as the caulking head is plastically deformed, and the holes 112a of the materials 112 and 113 to be fastened,
There is a problem that tensile stress is generated in 113a and durability is reduced. Further, when the material to be fastened is a resin having a lower strength than the rivet, there is a problem that whitening and creep occur to cause a decrease in strength. Therefore, when the resin is fastened, the caulking is performed by using a semi-tubular rivet, a full-tubular rivet, or the like so that whitening or creep does not occur. However, in the case of a full tubular rivet as well, swelling occurs in the rivet body (body), so that the cross section has the same area as the solid rivet, the diameter becomes large and it is necessary to set the cross section of the material to be fastened large. there were. Further, even in the case of a semi-tubular rivet, there is a problem in that a rivet diameter swells around the mouth of the end surface of the material to be fastened and a tensile stress is generated.
